season. These privations and discomforts, it must be remembered, 
were encountered not by a young beginner haying to make a way 
in life, but by a successful business man of mature years and large 
means, in the carrying-out of a self-imposed life-work, to which all 
Logan’s energies were devoted without stint or reserve. Besides 
personal work, large sums of money were often advanced when the 
necessities of the government led to the reduction of the annual 
grants for a term of years. The work thus partially outlined met 
at last with a hearty recognition both in the colony and in Europe, 
especially when the magnificent collections made during the progress 
of the Survey were exhibited in the different international exhibi- 
tions in London and Paris from 1851 to 1868. Logan received the 
honour of knighthood in 1856, and was made Chevalier of the Legion 
of Honour in 1855, and Officer in 1867. 
The more important portions of the scientific work of Sir W. Logan 
may, in the author’s words, be summed up as follows :— 
1. Investigations with regard to the origin of coal, which resulted 
in the establishment of the fact of the local origin of seams from 
growth in place. 
2. The establishment of the Laurentian system as a great group 
of stratified crystalline rocks divisible into several groups, and con- 
taining at certain horizons’evidences of organic life of the forami- 
niferal type (Hozoon canadense), the latter having been worked out 
jointly with Principal Dawson and Dr. Sterry Hunt. 
3. The proof of the existence of a newer series of crystallized 
stratified rocks, the Huronian, resting unconformably on the Lau- 
rentian. 
4. The identification of various formations younger than the 
Huronian, and the establishment of the fact that the lower paleo- 
zoic rocks rest unconformably upon the Laurentian and Huronian 
strata. 
5. The production of numerous admirable geological maps, in- 
eluding not only the work of his own survey, but that of the geolo- 
gists in the maritime provinces and the northern United States. 
The numerous official reports made at intervals during the progress 
of the survey formed the basis of the volume entitled ‘Geology of 
Canada,’ published in 1863, and which was the chief literary work 
of Sir W. Logan, in the preparation of which, however, he was 
largely assisted by Dr. Sterry Hunt. This is so well known that it 
will be unnecessary to go into detail as to its contents further than 
to state that it has been everywhere regarded as a model of what 
the geological handbook of a country should be, both as regards 
stratigraphical details and the accessory subjects of mineral and 
economic geology ; and in these respects, though now nearly twenty 
years old, it remains unmatched by any similar subsequent publi- 
cation. 
The large geological map on the scale of 25 miles to the inch was 
among the latest as well as one of the finest of Logan’s works, being 
remarkable for the beauty of execution and colouring. In the latter 
particular he took extreme pains; and the writer of the present
